v**d c. wrote

the product arrived after a very very long time,more exactly 90+ days the seller claims to be the postal ofice fault but its not because i bought more items through the same postal office and i had no problem,so the delay must be on the sellers part,on the other hand the product seems to be good

The item did not arrive, and the tracking info said the item did not have not arrived, but the seller only told me to wait when there was only 1 week left to the deadline of two months. They were not responsible for the delay and lost of the item, but they did not give me a good solution.

Compatibility of SSD disks the very bad! from 4kh working pieces of equipment I earned only on one! I don't advise this supplier! Delivery period tightened didn't come in time! NOT OFFSET!

The item purchased is working but I dont know if properly ... it 's a lot slower than I expected. I purchased your SSD to replace "HP Apacer" memory module, but Apacer is much faster than your module KingSpec. And it's also slower than the traditional 2.5" HDD for Notebooks. I thought that SSDs were absolutely faster than hard disk but on this subject is not so. Item received may be defective? ... I'm very disappointed.

WARNING: This drive does NOT support TRIM which drastically increases life. While the vendor claims the feature, this is not true. Unfortunately, I read the feedback of another customer after I purchased the drive to realize the fact. I verified it for myself under Linux (hdparm) as well as in Windows 8.1 and Windows 10, with AHCI enabled in BIOS. Check feedback from other customers, if you don't believe. I did that late. You have been warned. Please spend a bit more, get a good drive and do not fall for this trap. No wonder it's cheap!

There are a lot more bad feedback is out there on web about kingspec. So please be careful before you buy something from them.
